Abstract:This article introduces circulatation and managements by the spirit to float - water solution sour turn-the contact oxidize the craft in spinning and dying wastewater processing. Circulate the result enunciation, when inlet water BOD5 as 200-300 mg/ l, CODcr for 800-1200 mg/ l, outlet water attains the nation 《 the Spinning Dying industry water Pollution thing Exhaustion Standard 》 ( GB4287-92) medium second class exhaustion standard of the provision after processing. That craft has the characteristics of adaptability strong, the processing result stability, organic matter and the color degrees do away with the rate high etc. so the craft have the good foreground in spinning and dying wastewater processing.
Key word:The spinning and dying wastewater; BOT; Contact Oxidize Process Craft
